Myth Busted: Smoking Hookah Is Not Safer than Smoking Cigarettes

College kids everywhere take note: the myth that your post-class standby is safe just went up in smoke.

While it may come as a surprise to some, smoking hookah, a
water-based tobacco pipe, is no safer than smoking a cigarette. As the CDC
points out, an hour-long hookah session produces about 100 to 200 times
more smoke-filled air by volume than a single cigarette.

Researchers from the University of California at San Francisco
(UCSF) have confirmed in a crossover study of 13 smokers who use both
cigarettes and hookahs that a water pipe isn’t necessarily safer than a
cigarette. Contrary to popular belief (and the dreams of lounging
college students), a water pipe doesn’t remove all the harmful
substances from smoke. While hookah smokers don't consume as much
nicotine, they have an increased exposure to carbon monoxide (CO) and
the carcinogen benzene.

"The most surprising thing was the finding
of an usually high benzene exposure [from smoking hookah] that had not
previously been reported," said study author Neal Benowitz, M.D.,
professor of medicine at UCSF, in an interview with Healthline.

The
increase in benzene exposure from the cocktail of tobacco and additives
smoked through a water pipe is particularly worrisome. Exposure to high
levels of benzene increases a person's risk of developing leukemia.

And
while a decrease in nicotine consumption is technically a benefit of
hookah, the chemical is not altogether missing, meaning that it’s
possible to sustain a nicotine addiction by smoking a water pipe.

Taking Apart a Water Pipe

Though the International Agency for Research on Cancer
(IARC) estimates that 100 million people worldwide smoke tobacco from
water pipes, outside of Arab-American communities, a water pipe, of
which a hookah is just one variety, might sound a bit strange. Water,
smoke, and smoldering charcoal?

A water pipe is actually a
relatively simple contraption. A bowl of wet tobacco, often mixed with
some sort of flavoring, sits atop a chamber of water with connecting
hoses and mouthpieces. Burning coals are placed on top of the tobacco
bowl, aerosolizing the tobacco components, which are then sucked through
the hose, passing across water that cools the smoke and removes some
harsh irritants.

A common misconception is that a water pipe is
safe because the water acts as a filter, but it's a bit more complicated
than that, says Benowitz. While hookah tobacco typically contains only
five to 10 percent crude tobacco mixed with other substances like honey,
fermented sugar, and molasses, researchers from the University of Jordan report
that water pipe smokers are exposed to CO levels twice that of
cigarette smokers. This could potentially strain the heart and lungs of
someone with existing cardiovascular disease or risk factors like high
blood pressure.

"People believe that a water pipe is filtering
out carcinogens and toxins, but that's a misconception," Benowitz said.
In fact, because inhalation happens so fast, the toxins simply move
through the water and remain relatively intact. "What you're smoking is
different than what you're smoking in a cigarette, and while you're
smoking tobacco and dried fruit, you're also smoking
a charcoal briquette," Benowitz said.

While most people in the
U.S. only occasionally smoke hookah, this study demonstrates that
regular hookah smoking, or hookah smoking combined with cigarette
smoking, isn't any better for your health than regular cigarette
consumption. "It's not a benign substitute," Benowitz said.

While
this study was small, involving just 13 people, the participants came
from a range of ethnic backgrounds and were representative of a young,
diverse population. With an average age of 24 and an average body mass
index of 26, participants were relatively young and in good health. On
average, participants smoked 10 cigarettes per day and engaged in three
water pipe sessions per week, ranging from 45 minutes to one hour in
length.

A Myth Goes Up in Smoke

A water
pipe may give the impression of purifying smoke before inhalation, but
that’s simply a pipe dream perpetuated by tobacco manufacturers.

Sure,
hookah smoke contains different carcinogens than cigarette smoke, but
trading one set of chemicals and additives for the other isn't
advisable, especially for children and teens.
